Fan Casting Rhythm Thief & the Emperor's Treasure

In the city of Paris lives Raphael aka Phantom R, a thief unlike any other. While he does steal valuable items, he returns them days later. The reason is that his father disappeared 3 years ago leaving behind a coin with a strange marking. When he encounters a violinist girl whose violin bears the same marking, and a man claiming to be Napoleon whose casket was stolen 3 years ago, Raphael finds himself in a mystery that could shape the very face of Paris.
